Icons are common elements of web pages, the main function is Ideographic, also contains the role of decoration and brand transfer. Icons stored as GIF, PNG, and other bitmap formats, called pixel icons, are typically 16px, 24px, 32px, and so on. Of course, pixel icons can also be understood as pixel-style icons, not necessarily bitmap format exists, in this artic

What is the basic element of a color picture? To put it bluntly, an image consists of the basic thing is binary data, its capacity size in essence that is the number of binary data. A YUV422 image of a 1920x1080 pixel, the size of which is 1920x1080x2=4147200 (decimal), or 3.95M. This size is related to the number of pixel points and the storage format of the data. The following describes the relationship b

First, point Vs PixelIn iOS, when we use frames such as quartz,uikit,coreanimation, all coordinate systems are measured by point. The system will help us deal with point-to-pixel conversions when actually rendering to settings.The benefits of doing so isolate the change, i.e. we do not need to focus on whether the current device is retina after the layout, and can be laid out directly in a set of coordinate systems.In practice we need to keep this in

internal values of a pixel color to eight bits in a linear relationship to output to the screen, where red occupies three bits of the second bit, green occupies 3 bits in the middle and blue occupies 2 bits in the highest position. Windows regards the 8 bits as the index value of the logical palette. For example, after the color value of OpenGL (1.0, 0.14, 0.6667) is converted, the binary value is 10001111 (111 in red, 001 in green, and 10 in blue),

The getImageData and putImageData functions are required for Pixel processing in HTML5.GetImageData copies the pixel data in the canvas, processes the acquired pixel data, and finally passesPutImageData paste the processed data to the canvas. The process of processing pixels in the middle is called the batch processing of pixels. Because copying and pasting pixel

When I browsed the codepen, I stumbled upon some pixel art, remindi

As long as the digital signal processing circuit, there must be a clock signal. In the LCD panel, the pixel clock is a very important clock signal. The frequency of the pixel clock signal is related to the working mode of the LCD panel, the higher the resolution of the LCD panel, the higher the frequency of the pixel clock signal. Within a row, the number of

(For more information, see the source) This time we implement a custom transformation. The implementation of direct2d custom transformation shader models requires the implementation of HLSL (high level shading language. HLSL is a shader implementation, but HLSL can only be used in d3d. Shader is described as a short program executed by the video card, which can be executed efficiently (in parallel. Never learned? It doesn't matter. I don't know it either, but I won't explain it in detail here

1 Overview YUV is a color encoding method. It is developed to be compatible with black and white TVs. In Modern Color TV systems, three-channel color cameras or color CCD cameras are usually used to retrieve images, and then the acquired color image signals are divided by color, respectively amplified and corrected to obtain RGB, then, the Brightness Signal y and two color difference signal R-Y (U) and B-Y (v) are obtained through Matrix Transform circuit, and the three signals are encoded respe

Editor's note: Pixel style is the favorite of some artists, but also the game impression of many students.

Today, share an article about using Photoshop CS6 grid alignment to draw HD icon. Photoshop CS6 has been well received since its release, and attentive

Skills Make a commercial flash animation friends believe that the pixel font must be familiar. It's small and cool, very beautiful and popular with most designers. Currently like the very famous 04-series font in the country (Figure 1) (Fig. 1) Official website of the 04 series font:http://www.04.jp.org/ You can download all the 04-series fonts in this box. For the 04 series fonts, Flash support is not perfect. Not only for the 04 series, but for all

Recently I have studied pixel-level touch processing. Sometimes we use an irregular image as a button. This irregular image is a PNG image of a rectangle, it is very likely that the actual effective display content of the image only accounts for a small part of the entire PNG image, and most of the remaining content is the transparent area of the PNG image. We want to filter out this transparent area, A button response is effective only when the actua

When designing Web pages and program interfaces, most designers are worn out to ensure that each pixel's color, texture, and position are accurately presented. Accidentally, some of the most commonly used operations such as moving, rotating and pasting will make your hard work to naught. However, if you can make some small changes to your workflow, you can always keep the quality of the work in the project. 　　Pixel Perfect Rotation If you're not car

There is a way to see if someone is really careful when completing a webpage design. Sometimes the miracle is some small details, some details that are almost invisible to others. What I call "pixel-level beauty" refers to the careful scrutiny of online bars, edges, and border strokes. Instead of using a single line, we should add more details. The details can be a subtle gradient, or just a line of 1 pixel

Pixel depthIt refers to the number of BITs used by each pixel. The pixel depth determines the number of colors that each pixel may have, or determines the possible gray level of each pixel of a grayscale image. For example, each pixel
